Abstract

The invention discloses a blanking device of a kiln feeding system, which comprises an air chute, wherein a rigid impeller feeder is mounted at the middle part of the air chute, a lower inclined tube communicated with the air chute is mounted at the lower part of the air chute, the air chute on the rigid impeller feeder is provided with a bypass material tube, and the air chute under the rigid impeller feeder is provided with a bypass blanking tube; both the bypass material tube and the bypass blanking tube are communicated with the air chute, the lower end of the bypass material tube is communicated with the upper end of the bypass blanking tube, and a heavy-hammer flap valve used for blocking air is arranged at the upper part of the bypass blanking tube. The blanking device of the kiln feeding system is simple in structure, the purpose of the invention can be realized just by arranging the bypass material tube on the air chute on and under the rigid impeller feeder of an original blanking device; and the bypass blanking system is simple and reliable, the investment is low, and the maintenance is convenient.

Description

technical field [0001] The invention relates to the field of dry process production lines for cement production, in particular to all unloading systems. Background technique [0002] The 4000T / D clinker production line in our factory has continuously carried out scientific and technological innovation and transformation since 2011, and the current output has reached 4600-4700T / D. Since the equipment capacity of the 4.5×66M rotary kiln production line in our factory is configured below 4500T / D, and due to design reasons, the amount of ash returned from the kiln is too large. The actual output can reach 4500T / D only if the feeding amount reaches more than 330T / H. Due to the continuous increase in output, the insufficient feeding capacity of the kiln grid wheel is highlighted. During the production process, there are often failures such as material blocking in the chute and hoisting stop. In view of this bottleneck of production increase, we decided to add a bypass discharge ...
